The right to left shunt in TOF occurs by which of the the following route ?
-
RV- VSD- LV -Aorta
-
RV- Aorta
-
RV – VSD- Aorta
-
All of the above can occur
Answer : 2 Most shunting occur by direct streaming of RV blood into Aorta . If the aortic override is near 50 % it need not even cross the VSD in it’s circuit. (Although theoretically all of the above can occur)
